Successful Surgical Repair of Complete Duodenal Transection Caused by Horse Kick: A Case Report

Yusuke Asai, et al.

INTRODUCTION: Horse kicks are a rare cause of injury and tend to cause severe complications such as visceral organ injury. Traumatic duodenal injuries are associated with high mortality rates. Furthermore, their reconstructive procedures vary widely and require appropriate on-the-spot judgment by the surgeon. We experienced a case of blunt abdominal trauma with a complete transection of the first portion of the duodenum caused by a horse kick without any associated lesions. A good postoperative course was achieved by trimming the pyloric part of the stomach and performing an end-to-end anastomosis between the gastric remnant and the duodenum, along with tube decompression and biliary drainage.

A Case of Pediatric Retroperitoneal Schwannoma Presenting with Myoclonus of the Lower Limb: A Case Report and Review

Takazumi Kato, et al.

INTRODUCTION: Schwannomas arise from Schwann cells of the peripheral nerve sheath. Schwannomas are usually benign, and most of them are located in the head, neck, or distal extremities. The retroperitoneal region is an unusual location for schwannomas. Schwannomas are usually seen in adults and are very rare in the pediatric population.

Salvage Lung Resection of Aspergilloma Mimicking Tumor Regrowth after Immune Checkpoint Inhibitor Therapy for Stage IV Squamous Cell Lung Cancer: A Case Report

Takahiro Utsumi, et al.

INTRODUCTION: Recent advancements in chemotherapy, including immune checkpoint inhibitors, sometimes achieve complete remission in cases of stage IV lung cancer. On the other hand, immune-related adverse events may occur despite showing successful oncological effects. Herein, we report a rare case of a patient who underwent salvage lung resection after immune checkpoint inhibitor therapy for stage IVB lung cancer, which led to confirmed not only complete pathological remission but also complications with aspergilloma as a result of powerful effect for chemotherapy with immune checkpoint inhibitors.

Esophageal Atresia Caused by Corrosive Esophagitis for over 50 Years: A Case Report

Keisuke Fujimoto, et al.

INTRODUCTION: Corrosive esophagitis, often caused by the ingestion of alkalis, acids, or heavy metals, can result in severe esophageal damage and complications, such as stenosis or closure. Although initial treatment is conservative, surgical intervention is necessary when a chronic stricture occurs. A case of esophageal atresia persisting for 50 years due to corrosive esophagitis has not yet been reported. Here, we describe such a case.

A Case of Sigmoid Colon Perforation Associated with Sodium Zirconium Cyclosilicate in a Patient with Advanced Rectal Cancer

Takaki Kamiya, et al.

INTRODUCTION: Sodium zirconium cyclosilicate (SZC) binds with potassium in the gastrointestinal tract and increases fecal potassium excretion. Since SZC is a novel and non-swelling drug, the risk of intestinal perforation is not mentioned in the package insert. We hereby report the case of sigmoid colon perforation caused by hard stools and severe hypokalemia in a patient suffering from advanced rectal cancer, who was taking SZC.

Longitudinal Pancreatojejunostomy for Pancreaticodigestive Reconstruction in the Resection of Pancreatic Head Malignancy with Chronic Pancreatitis: A Case Report

Hironori Hayashi, et al.

INTRODUCTION: With progress in pancreatic surgery, a preservation of residual organ function has become more important. Pancreatic malignancies are occasionally accompanied by chronic pancreatitis (CP) and pancreatolithiasis (PL). Longitudinal pancreatojejunostomy (LPJ) is reportedly a useful method of surgical management in cases of CP with PL. We describe a patient with pancreatic head intraductal papillary mucinous carcinoma (IPMC) concomitant with PL, who underwent subtotal stomach-preserving pancreaticoduodenectomy (SSPPD) and LPJ for reconstruction.

Multiple Desmoplastic Small Round Cell Tumor in the Intestine: A Case Report

Naoto Tsujimura, et al.

INTRODUCTION: Desmoplastic small round cell tumor (DSRCT) is a highly malignant sarcoma and an extremely rare tumor, predominantly found in the abdominal and pelvic regions. Here, we report the case of a patient who underwent surgical treatment for multiple desmoplastic round cell tumor in the intestine.

A Case of Appendicitis Due to Burkitt Lymphoma Masking the Systemic Symptoms of Rapidly Progressing Burkitt Lymphoma

Tomoya Masuda, et al.

INTRODUCTION: Primary malignant lymphoma of the appendix is a rare disease, and primary Burkitt lymphoma of the appendix has been reported very rarely in Japan. Burkitt lymphoma is an aggressive lymphoma that progresses more rapidly than other malignant lymphomas, making it sometimes difficult to distinguish between systemic symptoms, such as fever associated with lymphoma progression and fever caused by appendicitis.

Impact of Right Top Pulmonary Vein Location on Subcarinal Lymph Node Dissection in Thoracoscopic Esophagectomy: A Case Report and Literature Review

Takeshi Horaguchi, et al.

INTRODUCTION: The right top pulmonary vein (RTPV) is a rare anatomical variant that arises independently of the right superior lobe. It drains behind the right main bronchus or bronchus intermedius and into the left atrium or another pulmonary vein. This anomaly poses challenges during subcarinal lymph node dissection in thoracic surgery, such as esophagectomy, owing to the risk of vascular injury.

Tracheal Obstruction by Thyroid Gland Extension into the Trachea after Blunt Tracheal Transection

Hironori Ishibashi, et al.

INTRODUCTION: Tracheal injuries due to blunt force trauma are rare yet life-threatening conditions, comprising only 4% of chest trauma cases. Diagnosis is often delayed, increasing the risk of severe complications. This report describes a unique case of tracheal obstruction caused by thyroid gland extension into the trachea following blunt trauma, which was managed successfully with venovenous extracorporeal membrane oxygenation (ECMO) and surgery.

Rare Metastatic Mesothelioma Occupying Intra-Atrial Cavity, Released by an Emergency Surgery: A Case Report and Literature Review

Tomohiro Takano, et al.

INTRODUCTION: Cardiac surgery for cardiovascular-associated mesothelioma has a poor prognosis. However, life-saving surgery is unavoidable to maintain circulation. This report describes a case in which metastatic intracardiac mesothelioma triggered sudden respiratory failure, which was reduced by surgical resection.

A Multimodal Approach Utilizing Balloon Occlusion for Postpancreatectomy Hemorrhage: A Case Report

Aya Maekawa, et al.

INTRODUCTION: Postpancreatectomy hemorrhage (PPH) is a life-threatening complication following pancreaticoduodenectomy, requiring prompt and accurate diagnostic and therapeutic measures to ensure patient survival.
